Cement Clinker - an overview ScienceDirect Topics

Within the definition of CEM I is white cement, manufactured from especially pure chalk or limestone, with china clay (low in iron) and white sand as sources of silica. Such an unreactive mix requires power-consuming sand grinding, and very high clinkering temperatures (~ 1600°C).

What is Cement Clinker? Composition, Types Uses - Civil ...

2 天前  Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
